Abstract

The invention discloses a yarn nozzle lifting device in a flat knitting machine. The yarn nozzle lifting device comprises a Uz seat, a Uz handle, a synchronous belt cover plate and a synchronous belt. The upper end of the Uz handle is arranged in the middle of the Uz seat, and a drive pin is arranged on the Uz handle. A limiting block is fixed behind the Uz seat, and a movable channel is formed between the Uz seat and the limiting block. The synchronous belt is arranged in the movable channel between the Uz seat and the limiting block. The synchronous belt cover plate is arranged above the Uz handle, and the two ends of the synchronous belt cover plate are fixed to the synchronous belt through fixing blocks. An inverted-V-shaped movable groove is formed in the middle of the synchronous belt cover plate, and the drive pin on the Uz handle is arranged in the inverted-V-shaped movable groove of the synchronous belt cover plate. The motion track of a yarn nozzle is controlled by dragging the synchronous belt cover plate by the synchronous belt, and the yarn nozzle carries out weaving when at the low position of the inverted-V-shaped movable groove. The yarn nozzle does not carry out weaving when at the high position of the inverted-V-shaped movable groove, and therefore the yarn nozzle collision problem is solved.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, in particular to a yarn feeder lifting device in a flat knitting machine. Background technique [0002] The computerized flat knitting machine controls the yarn feeder to start or stop working anywhere within the weaving width range by computer signals. In order to weave more complex intarsia structures more effectively, most computerized flat knitting machines also need to be equipped with special intarsia yarn feeders. , After knitting a certain color area, the intarsia yarn feeder needs to rise according to the program and leave the working state to avoid collision with the knitting needles of the next color area. Most of the existing intarsia yarn feeders have the function of lifting the yarn feeder, which can drive the yarn feeder to move up and down through the corresponding driving structure according to the specific work needs. However, the drive structure of the existing inta...
